Nitrogen (N) is the most important element that controls plant growth. During the past twenty years, our understanding of which N species are important for plant growth has developed significantly but it is still thought that large nitrogenous molecules need to be broken down into their constituent amino acids to be available for plant and microbial growth. This paper builds on our understanding of this process and suggests that small peptides are equally important for microbial nutrition and that soil microbes outcompete plants for low molecular weight N compounds in maritime Antarctic soil.

These resources were initially developed to support candidates of the Language Skills Certificate. The resource includes information about the Certificate, supporting learning resources, video examples and past papers. The purpose of the resources is to assist candidates in the Language Skills Certificate to prepare for their assessments. However, they are available free of charge, and are suitable for anyone who wants to improve their Welsh language skills. The register is now closed for this academic year.

The geographical distribution of Ophelia bicornis is restricted to the coasts of the Mediterranean Sea, the Black Sea and the western coast of Europe as far as Brittany and southern parts of Great Britain. Within this wide reach, the worm is restricted to very narrow areas (in the context of the rise and fall of the tide) of sand which are generally unsuitable for sustaining populations of animals and plants. Despite this, Ophelia is shown to succeed and flourish there, depending, to a large extent, on physical and physiological adaptation.
